chocolateyfeature should set setExplicitly to true

[brajjan]

Use Case

When changing a chocolateyfeature to enabled it only sets the "enabled" property to "true" (this is how chocolatey defines its default values) and does not care about the "setExplicitly" property.

eg.

chocolateyfeature { 'exitOnRebootDetected':
  ensure => 'enabled',
}

Notice: /Stage[main]/Main/Chocolateyfeature[exitOnRebootDetected]/ensure: ensure changed 'disabled' to 'enabled'

PS> Get-Content C:\ProgramData\chocolatey\config\chocolatey.config | Select-String exitOnRebootDetected

<feature name="exitOnRebootDetected" enabled="true" setExplicitly="false" description="Exit On Reboot Detected - Stop running install, upgrade, or uninstall when a reboot request is detected. Requires 'usePackageExitCodes' feature to be turned on. Will exit with either 350 or 1604. When it exits with 350, it
means pending reboot discovered prior to running operation. When it exits with 1604, it means some work completed prior to reboot request being detected." />

Describe the Solution You Would Like

When setting a chocolateyfeature to "enabled" it should care about and set the setExplicitly value to true aswell

Additional Context

This could be addressed by having the chocolateyfeature provider also look at / change the setExplicitly
Will make a PR for this aswell
